Tamoxifen derivative-1
Tamoxifen derivative-1 is a derivative of Tamoxifen (HY-13757A) with reduced affinity for estrogen receptor (ER). Tamoxifen derivative-1 blocks estrogen-induced activity, inhibits estrogen-stimulated uterine growth, and exhibits uterotrophic activity in immature rats. Tamoxifen derivative-1 can be used in research related to breast cancer.

Activité biologique
Tamoxifen derivative-1 (Compound 13) binds to estrogen receptors in rat uterus, with a relative affinity of 0.2% that of estradiol[1].
Tamoxifen derivative-1 (48 h) inhibits estradiol-dependent transcriptional activation in HeLa cells via wild-type hERα[2].
Tamoxifen derivative-1 (1000 nM; 48 h) acts as a partial agonist of ERα-dependent transcription in HepG2 cells; the ERαD351A/V mutation abolishes this activity, the ERαD351E mutation increases its activity to the level of tamoxifen, while the ERαD351Y mutation maintains its activity at a moderate level[2].

Animal Model:Holtzman (immature female, 20-22 days old)[1]
-
Dosage:5 μg/day; 15 μg/day; 50 μg/day (antiuterotrophic activity); 50 μg/day (partial estrogen agonist activity)
-
Administration:s.c.; daily; 3 days
-
Result:Stimulated uterine wet weight to dose-dependent levels, reaching approximately 60 mg at 50 μg/day.
Reduced estradiol-stimulated uterine wet weight from ≈100 mg to approximately 60 mg when co-administered with 1 μg/day estradiol at 50 μg/day.
Had a relative estrogen receptor binding affinity of 0.2% compared to estradiol (set at 100%).
